LOUIS, MISSOURI.

OIL-FILTER.

Application filed February 1 To all whom, it may concern:

Be it known that I, Josnrn B. BELL, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Oil-Filters, of which the following is a specification, containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to an oil-filter; and the object of my invention is to provide a simple inexpensive apparatus whereby dirty oil may be easily and quickly filtered, so that it isseparated from all impurities.

A further object of my invention is to construct an oil-filter wherein a proportionately large filtering area is obtained in a limited space and which filter may be readily cleaned.

To the above pur oses my invention consists of certain nove features of construction and arrangement of parts, which will be hereinafter more clearly set forth, pointed out in the claims, and illustrated in the accompanying drawings, in whieh Figure 1 is a perspective view of a filter of my improved construction. Fig. 2 is a vertical section taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged vertical section taken on the line 3 3 of Fig. 1.

In the construction of my improved filter I make use of a suitable receptacle 1, preferably rectangular in form and provided with a removable cover 2. Located on the interior of the receptacle, a short distance below the top thereof, are the inwardly projecting flanges 3. Removably located on these fianges 3 is a plate 4, in the center of which is formed a depression 5, into which the dirty oil is poured when being placed in my improved filter. Located in this depression and passing therethrough is a short tube 5, the upper end of which is normally closed by a suitable cap or plug. Seated in the bottom of this depression 5 and extending downwardly therefrom is a tube 6, which terminates slightly above the bottom of the receptacle 1. Located in the depression 5 over the upper end of the tube 6 is a screen 7, which prevents large articles of dirt, straw, or shavings and the like from entering and clogging up the tube 6.

The filtering-bed of constructed in the form of a deep my improved filter is basket and Specification of Letters Patent.

composed of four side walls and a bottom, all of which are constructed of sections 8 of wire mesh arranged parallel with each other, and the space between all of the parallel sections is filled with mineral wool 9 or analogous fibrous material. The top of the basket so formed is secured in any suitable manner to the under side of the plate 4 and extends downwardly into the receptacle 1. Located on the outside faces of the sections 8 of wire mesh are sections 10 of cloth or other woven material, and which sections are held in place by being stitched to one another through the walls and bottom of the filteringbed, as indicated by 11. The lower end of the tube 6 passes through the bottom of the filtering-bed, and lock-nuts 12 are located above and below said bottom upon said tube in order to rigidly hold the parts together.

Located through the bottom of the filtering-bed to one side of the tube 6 is a short tube 13, to the lower end of which is secured an elbow 14, and carried by said elbow is a short section of flexible tubing 15. Passing through the front wall of the receptacle 1, adjacent the bottom thereof, is the rear end of a faucet 16, with which the forward end of the flexible tube 15 connects, A second faucet 17 is arranged in the front wall of the receptacle 1, adjacent the bottom thereof, and is for the purpose of allowing the discharge of the dirty oil from the receptacle 1 when the filter is being cleaned. A glass gage 18 of ordinary construction is arranged on the front face of the receptacle 1 for the purpose of indicating the amount of dirty oil in the filter.

In the use of my improved filter the dirty oil is poured into the depression 5 and passes from thence downwardly through the pipe 6 and discharges into the bottom of the receptacle 1. From thence said dirty oil rises around the side walls of the filtering-bed, and by capillary attraction and pressure said oil asses through the side walls and bottom of the filter-bed to the interior of said bed, and in so doing is freed from all dirt and impurities. The clean oil from the interior of the filter-bed discharges therefrom through the sive, and

where a considerable depth of dirty oil is maintained in the receptacle 1 the pressure resulting therefrom materially assists in said filtering action.

en it is desired to cleanse the filteringbed, the dirty oil is all discharged from the rece tacle 1 and a cleansing liquid-such as coaloi, gasolene, or benzin-is poured throu h the tube 5 into the interior of the filter-bed, and as said liquid passes through the bed it will effectually remove all the dirt therefrom.

The flexible tube forms a convenient means of connecting the filtered-oil outlet from the interior of the filtering-bed with the clean-oil faucet 16.

The filters are preferably made rectangular in order that a number of them can be arranged in battery form side by side without the loss of floor-space which results when a number of round receptacles are located side by side or in battery form.

My improved filter is very simple, inexpencompact, acts very rapidly where a high level of dirty oil is outer receptacle, and can be very quickly and easily cleaned. a

claimv 1. An oil-filter, constructed with a receptacle, a plate removably positioned in the upper end thereof, a filtering-bed in basket form carried by said plate and extending downwardly into the receptacle, a tube leading from the plate downwardly through the bottom of the filtering-bed, and a tubular connection leading fi'om the interior of the filtering-bed to the exterior of the receptacle substantially as specified.

2. An oil-filter, constructed with a receptacle, a plate removably arranged in the top thereof in the center of which plate is formed a depression, a filtering-bed in basket form carried by said plate and extending downwardly into the receptacle, a tube extending downwardly from the depression in the plate through the bottom of the filtering-bed, a short tube through the bottom of the filtering-bed, an outlet in the lower end of the receptacle, and a flexible tube from the short tu e to said. outlet; substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
